5.3Storage System Connection Mode
5.3.1 Difference between Traditional Photovoltaic System and Storage System Growatt SP 2000 series storage plus can be connected to single-phase grid-connected inverter to build a
storage-function system. Every string can be connected to one SP 2000. If you have double MPPTs to be connected
to SP 2000 respectively, every MPPT connects one will be feasible.
The traditional single-phase inverter system is shown as below:
Chart 5.6
Traditional single-phase inverter system consists of PV panels, PV inverter, load and power grid. The inverter
supplies the power generated by solar panels to household load. Extra electricity will be fed to the grid when
generated power is more than family load needs; otherwise inverter will get power from grid for supplement.
PV Storage System with the storage plus is shown as below:
Page 16/43
Chart 5.7
Compared with the traditional photovoltaic system, a storage-control device SP 2000, battery cells and a sensor for
information collection have been added into the Storage System (Notice: Sensor must be installed close to the grid
side).
5.3.2 Storage System installation with Dual-MPPT inverter As for connection with single MPPT inverter, you can refer to 6.4.1 for installation. When installing the storage
system with dual MPPT inverter, if you just upgrade one MPPT to execute storage function, you are advised to
install the Storage Plus to the MPPT which generates greater power. Installation diagram as below:
Chart 5.8
Connect one PV string to the Storage Plus, and then to one MPPT of the inverter. While connect the other PV
string direct to the input terminal of the inverter.
If both MPPTs are to be upgraded to execute storage function, installation should be done as below:
Page 17/43
Chart 5.9
Notice: During the installations above ,please pay attention to the installation position of the sensor.
5.3.3 Installation steps of Upgrading existing PV system Steps to add the storage system into the original installed PV inverter system are shown as follow:
Step 1: If inverter is equipped with a DC switch, please turn the DC switch to Off and ensure that the DC switch on
the Storage Plus stays at Off status at the same time. Then unplug the terminal connected to the inverter
from PV panels, and connect it to the Input terminal of Storage Plus.
Chart 5.10
Step 2: Connect the output of Storage Plus to the input of your PV inverter, as the diagram show:
Chart 5.11
Step3: Connect the battery to Storage Plus, you can refer to 5.4.7 for connection of battery.
Page 18/43
Chart 5.12
Step 4: Buckle the sensor to the residential user inlet wires, at the same time plug the AC PLUG on the Storage Plus
to electricity, and finally the entire system is ready to work smoothly.
Chart 5.13
5.4 System Electrical Connection
5.4.1 Storage Plus AC power supply connection Preparations before connection:
A measure the grid voltage and frequency and make sure the voltage is 220/230Vac , the frequency is 50/60Hz in
single phase.
B Connect the AC cable with safety regulation to the AC PLUG section.

When it is unnecessary to install the NTC battery, please insert the RJ45 plug of the sensor into the section marked
with the words: NTC/SENSOR.
Chart 5.20
Remark: Sensor lead wire (5m in length) specification: RJ45, standard LAN line (one end with 8P modular plug, the
other connected with sensor). But if the length is not enough, customer can add cable, so the length can be
increased to 15m, the operation is as follow chart:
Page 22/43
Chart 5.21
During the actual operation, please pay attention to the installation of current transformer as the diagram shows
below:
Chart 5.22
As illustrated above, open the current transformer and you can see an arrow labeled on it indicating the
direction of current. Put the live wire among the under-detection wires onto the current transformer. After latching
the current transformer, the installation has been finished.
Notice: the direction (from K to L) of the arrow on the current transformer is corresponding to the direction of
the current in live wire from load to the grid.
Page 23/43
5.4.5 Connection of LAN Monitoring
If you need to monitor the Storage Plus via LAN, the installation steps are as follow:
1. Make sure the cover plate is removed.
2. Make the LAN line go through the second hole of the cover plate, and insert it into the plug under the

6.2 Operation modes
6.2.1 Normal charge mode
When daytime with abundant sunlight, energy storage machine can work in normal charge mode.
● When DC voltage is more than 150V,The energy storage machine detected the inverter has countercurrent
power flow to the grid, The machine would transform the redundant energy exist in PV panel into electric and
store into the battery, the green LED light will be lighten at the moment
● When DC voltage is less than 130V, The energy storage machine will quit the normal charge mode
automatically and turn into standby status, until the PV voltage up to grade again and there is countercurrent
power, the energy storage machine would turn into normal charge mode automatically.
● When DC voltage is more than 150V,while The energy storage machine fail to detect the inverter has
countercurrent power flow to the grid, the energy storage machine won’t start charge, and in the standby
status.
NOTICE: Must connect to AC, or the energy storage machine won’t start up.
6.2.2 Normal discharge mode
When the solar energy is shortage at night, though battery capacity is completely over plus, then the energy
storage machine can work in normal discharge mode.
● When DC input voltage is less than 100V, The energy storage machine detected the inverter has downstream
power flow from grid to load, the energy storage machine will extract energy from the energy storage battery
side, and provide it to inverter as the photovoltaic panel’s mode, meanwhile the inverter transform the DC
current into AC current and feed it to load, the green LED light will be lighten at the moment.
● When DC voltage is less than 100V, The energy storage machine fail to detect the inverter exist downstream
power flow from grid to load, then the energy storage machine will be standby state, and won’t provide any
power.
● When DC voltage is more than 120V,the energy storage machine will transform discharge state to standby
state.
NOTICE: Must connect to AC, or the energy storage machine won’t start up.
6.2.3 Fault mode
The energy storage machine’s intelligent control system could monitoring and adjustment system’s status
continuously, when energy storage machine monitoring anything unexpected happen, such as system fault or
machine fault ,the LCD will display the fault information, in fault mode, the LED light will be lighten.
NOTICE:

8 Attention of the installation environment, maintenance and cleaning
Heat dissipation performance is very important when Energy storage machine work under the environment of
high temperature, better heat dissipation can reduce the possibility of energy storage machine stops working.
Growatt SP series storage machine without fan so belongs to natural cooling, hot air from the top of the radiator,
tie-in battery, use environment for IP20, please pay attention to the temperature of the installation environment, to
ensure that the battery's safety and the normal work of the machine.
If the storage machine doesn't work for overheating too cold, solve it according to the following methods
confirm whether the radiator air duct installation is reasonable, choose the appropriate position before
installation.
If is lead-acid batteries, confirming the NTC battery is in a good installation
confirm whether the battery temperature is too high, the battery temperature too high can also lead to
energy storage machine fail to work normally, at this point, to ventilation, cooling or still handle to the
battery, please.
If temperature is low, also can appear the battery low temperature protection, the battery will start with
small load in low temperature output, when after temperature back to normal can work normally,
please be patient at this time
if the temperature is too low, it is possible the battery low temperature protection rather than the output,
at this time, please pay attention to the working temperature range listed in the specifications of the
book
